Ghost of Yotei hitches during fast travel on my Zotac RTX 5070 Ti 16GB. Memory clock fix?

Galloping through those stunning landscapes is incredible, but the occasional micro-stutter at 4K is just jarring. The 16GB VRAM on the Zotac RTX 5070 Ti was having these bandwidth swings between 600-800GB/s while streaming huge textures, which caused brief resource bottlenecks. I tried turning on DLSS Frame Gen, and while the FPS doubled, the input lag felt mushy and the hitches were still there. I went into the NVIDIA Control Panel, set power management to 'Maximum Performance,' and used a tool to lock the memory clock at its peak to kill the fluctuations. My response time monitoring showed the latency peaks dropping from 22ms to a tight 7-11ms. The game is now buttery smooth. I did run into a weird issue where the GPU fans started resonating and making a humming noise after locking the clocks, but a quick tweak to the fan curve silenced it. GPU temps are stable at 64-70℃. After several scene tests, the hitching is gone and frame times are locked at 4.2-5.8ms.
